Industrial IoT is not short on data—PLCs, energy meters, sensors, and VFDs already speak RS-485. What they lack is a reliable, low-power, long-range wireless bridge to the cloud.
KC25x LoRaWAN DIN-Rail RS-485 Data Concentrator is built exactly for that.
Ultra-Compact, Fits Anywhere
Measuring just 69.0 × 25.0 × 25.0 mm, KC25x snaps onto standard DIN rails or integrates directly via its board-level interface. The 4-pin 2.54 mm-pitch terminal (V+ / V- / A / B) keeps RS-485 wiring simple and tool-free.
Wide-Range Power, Harsh-Field Ready
Accepts DC 5–24 V directly; with an external adapter, AC 85–270 V is also supported. Quiescent current stays under < 8 mA, peaking at only < 110 mA during LoRa TX at 22 dBm. Whether battery-backed or line-powered, KC25x keeps energy budgets lean.
Multi-Band, Global-Ready
KC25x covers six regional frequency bands out of the box: CN470 / EU433 / EU868 / AS923 / AU915 / US902
One hardware platform. APAC, Europe, North America, or Oceania—same SKU, less complexity.
Industrial-Grade Reliability
Operates flawlessly from -40 °C to +85 °C in up to 95% non-condensing humidity, with IP53 protection. From freezing winters to tropical wet seasons, KC25x delivers 24×7 uptime.
Class C + 22 dBm: Always Listening, Instantly Reactive
KC25x runs in LoRaWAN Class C mode—the end-device continuously listens for downlink. Cloud commands reach the terminal instantly without waiting for an uplink window. Combined with +22 dBm TX power and -142 dBm RX sensitivity (SF=12, BW=125 kHz), a single gateway can cover several kilometers in urban environments.
Dual join methods (OTAA / ABP) are supported, with typical network join time of 6–8 seconds.
EdgeBus Inside—When a DTU Becomes Truly Smart
KC25x is powered by the EdgeBus (EB) engine. Developers can write custom edge logic using the EB SDK and EB-compiler:
- RS-485 transparent transmission with native Modbus RTU support
- RPC passthrough (51hex)—the cloud can read and write RS-485 devices directly
- COV (Change of Value) reporting to conserve airtime
- FUOTA for remote firmware upgrades—no more site visits
A traditional DTU just moves raw bytes. KC25x parses protocols, filters data, and triggers alarms at the edge—reducing cloud bandwidth and platform load.
Plug Into Any Major LoRaWAN Network
KC25x works seamlessly with ThinkLink, ChirpStack, The Things Network (TTN), and other standard-compliant LoRaWAN network servers. No vendor lock-in—you choose the network.
Typical Applications
| Use Case | Details |
| Remote PLC / VFD Monitoring | RS-485 Modbus RTU via LoRaWAN to ThinkLink / ChirpStack |
| Power Distribution & Metering | DIN-rail mounting, multi-meter RS-485 bus aggregation |
| Environmental Sensor Networking | Wind speed, temperature, humidity, and noise sensors unified via KC25x |
| Smart Agriculture / Water Management | Pumps, level meters, and flow meters over LPWAN |
